Our Bolting Services

CWind has an established track record of completing multiple scopes of construction and bolting solutions for offshore wind projects across the UK and Europe.

Offshore wind turbines are built to withstand high levels of vibration, which can lead to tensile stress of bolts and subsequent wear on joints. As well as vibration, the reliability of joints may be compromised by bolt relaxation, fatigue and corrosion. If not properly maintained bolt wear and tear may potentially result in joint separation and ultimately in complete joint failure.

CWind has a wealth of experience delivering successful bolting services during offshore wind turbine assembly, ensuring accurate tensioning and loading, providing reliability, value and consistency of offshore wind projects.

Utilising our trained technicians, bolting teams, and experienced project managers, combined with a fleet of owned CTVs, CWind is able to effectively meet clients’ needs, and ensure asset integrity.
